I believe it was Tom Christiansen that said during a
talk on Perl at a Lisa Conference "a variable in
Perl only lives as long as someone cares about it".
Meaning that if you undef it or otherwise stop referencing
it Perl will get rid of it. What is not clear to me is
if Perl will release the memory back to the system or
if it will just make it available for other variables to
use.
